Thermal Overload Relay RTO 2 - 15 - 21 A

About this product
Lauritz Knudsen Type RTO thermal overload relays are bimetallic motor-protection relays suitable for MO series contactors. RTO 1, RTO 2 and RTO 3 mount directly on MO 9-45, MO 50-70 and MO 80-110 contactors respectively and are directly operated; RTO 4 is CT operated and separately mounted for larger motor ratings. Features include ambient-temperature compensation up to 55 deg C, built-in single-phasing protection, manual and auto reset, front access to START and STOP/RESET buttons, and sealable OFF condition. Conforms to IS/IEC 60947-4-1 and IEC 60947-4-1.

The Lauritz Knudsen CS96366OOCO is a thermal overload relay with an adjustable setting range of 15–21A. It mounts directly on MO 50 - 70 contactors. It protects motors against overload when used with a matching contactor.
Choose the Lauritz Knudsen CS96366OOCO when your motor's full load current falls within 15–21A — or, in a star-delta starter with the relay in the winding circuit, when 0.58 × the full load current does. Setting the relay to the motor's nameplate current protects the winding from sustained overload.
Overload relays are used with contactors in motor starters, such as DOL and reversing starters, to protect motors against sustained overload.
Set the relay to the full load current shown on the motor nameplate, and make sure that value lies inside the relay's adjustable range. Choose a trip class that suits the motor's starting time. In a star-delta starter the setting depends on where the relay is connected, so follow the starter's wiring diagram.
